The EUT is set to transmit in a continuous mode. High-Q Cavity Notch filters are used to reduce the amplitude of the intentional transmitter and prevent overload of the system preamplifier. The EUT is fixed to a pole and placed 80 cm above the ground plane for measurement below 1GHz and Above 1GHz. For Above 1GHz, the antenna bore sight is at 1m. The antenna to EUT distance is 3 meters. The EUT is configured in accordance with ANSI C63.10. The EUT is set to transmit in a continuous mode. For measurements below 1 GHz the resolution bandwidth is set to 100 kHz for peak detection measurements or 120 kHz for quasi-peak detection measurements. Peak detection is used unless otherwise noted as quasi-peak.…
